Fieldpiece SM382V Wireless 3-Port Refrigerant Manifold SM382V — Digital Gauges with Micron Vacuum and Data-Logging

Fieldpiece SM382V is a wireless, three-port digital refrigerant manifold with an integrated vacuum (micron) gauge built for accurate HVAC and refrigeration service, offering pressure, superheat, subcooling and temperature measurement in one handheld tool.

The SM382V combines Fieldpiece's SMAN family digital manifold electronics with a dedicated micron vacuum gauge and wireless connectivity so technicians can diagnose systems faster and with fewer cross-check tools. It measures low and high side pressure, calculates superheat/subcooling, accepts protected thermocouple probes, and logs job data for later review. Robust construction, four-valve routing, and compatibility with Fieldpiece Job Link accessories make it a versatile centerpiece for residential and light-commercial servicing.

How does the SM382V improve measurement accuracy on refrigerant systems?

The SM382V uses precision digital sensors to read low and high pressures, then applies temperature inputs to compute superheat and subcooling reliably. The dedicated vacuum (micron) gauge helps confirm system evacuation to proper deep-vacuum levels, reducing uncertainty when charging or repairing systems.

• High-accuracy low and high pressure sensors for repeatable readings
• Automatic superheat and subcooling calculations using temperature probes
• Micron-level vacuum readings for proper evacuation verification

What connections and probes can I use with this manifold?

The SM382V features three service ports (3-port configuration) and protected thermocouple jacks for pipe and ambient temperature measurement. It also supports Fieldpiece Job Link psychrometer probes and other thermocouples, which expands diagnostic capability for airflow, temperature differentials and system tightness tests.

• Three service ports for low, high and auxiliary connections
• Protected thermocouple jacks for pipe and outdoor sensor use
• Compatibility with Job Link psychrometer probes and Fieldpiece accessories

Can the SM382V handle data logging and system tightness tests?

Yes — the SM382V includes data-logging features and a temperature-compensated system tightness test to document vacuum holds and leakage checks. Saved logs help technicians review jobs, compare before-and-after conditions, and present findings to customers or for compliance records.

• Onboard data logging for pressure, temperature and micron readings
• Temperature-compensated tightness test for more accurate leak verification
• Wireless telemetry for remote viewing and job documentation

How does wireless connectivity benefit field service workflows?

Wireless capability lets technicians view live readings from a distance, reducing safety risks near running equipment and allowing one-person operation during complex service tasks. Remote readout also streamlines documentation and sharing of data for job records or team troubleshooting.

• Live wireless telemetry to handheld devices or Fieldpiece apps
• Enables single-tech operation during charging or evacuation
• Simplifies job data transfer and collaboration with colleagues or customers

Who is this for: The Fieldpiece SM382V is aimed at HVAC and refrigeration technicians who need a compact, accurate manifold that combines pressure, temperature and vacuum measurement into a single handheld instrument. It's well suited for residential and light-commercial service techs who perform charging, evacuation, system troubleshooting and documentation, and for shops that want wireless data logging and compatibility with Fieldpiece Job Link accessories.
